COATING MACHINE.

Application filed Ha es, 1921. Serial No. mazes.

To all whom it'may concern 3 Be it known that we, CHARLES L. HOOPER, ROBERT F. SUTHERLAND, and ALBERT W. PARKHoUsE, citizens of the United States, and residents of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Coating Machines, of which the following is a specification.

The present invention relates to coating machines and an object thereof is to provide a machine which will effectively hold and turn an object during the coating thereof. Another object thereof is to provide means for supporting an object such'as a barrel in such a position that it may be effectively engaged by the holding and turning means while upon the support and removed from the support so that no interference with the supportoccurs during the turning. Still another object of the invention is to provide a coating machine inwhich the object is supported and turned during the coating with adjustments adapted to accommodate objects of different lengths and diameters. Another and further objectvof the invention is to provide a supporting means which will sustain a barrel in a posi tion over a coating receptacle where it may be engaged by a holdmg and turning means to be removed from such supporting means by the holding and turning means, the lat 'ter returning the barrel to "the support.

To these and other ends the invention consists of certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the embodiment of the invention herein illustrated, there is provided a frame which, in this instance, comprises two base pieces 1 on which a cross piece 2 is supported, this cross piece having standards 3 rising therefrom, four of such standards being provided, two at each side of the frame, and these standards in turn being connected by a top piece 4. Also supported on the base pieces are cross pieces 5 which form supports for a tank or receptacle 6 in which the aint or coating material is contained.

The barrel 7 or other object to be coated is supported above the coating tank or receptacle 6 by a suitable turning means comprising in this instance two relatively adjustable turning heads, each of which, comprises preferably a disk 8 and a plurality of barrel chime engaging members 9 which have chamfered faceslO for engaging such chimes and which are removably secured to the disk 8,'the'disk in this .nstan'ce, be-- ine provided with radial slots 11 in which b ts 12 operate, said bolts engaging clamping plates 13 on the rear faces of said disk- It is apparent that the chime engaglng members each may be removed and other chime engaging members having chamfered faces or different arcs substituted and positioned at different distances from the center of the disk. The turning heads are each provided with a shaft, this shaft being indicated at 14 for one head and 15 for the other head, both being journaled in the upright 3. The shaft 14, in addition to being mounted to turn, is adjustable longitudinally and to this end it has an abutment piece 16 fitted about the same so that the shaft turns there'- in and it projects from opposite sides of the shaft. such abutment piece being arranged between two collars 17 fixed to the shaft and the two projecting arms being adapted to engaged within notches 18 formed in two projections-19 on one of the uprights 3, as shown in Figs. 14 and 15. This adjustment is provided to accommodate barrels of different heights. It is apparent that, when the abutment piece 16 is free from the proje tions 19, as shown in Fig. 14, a barrel of greatest height may be held between the =wo heads, whereas, when this abutment p ece is secured in notches 18, nearer to the uprights3, barrels-of less height may be held between the heads. Movement of the other head may be eftected through a lever 20 pivoted at 21 to one the uprights 3 and connected by a link 22 with a slide 23 moving on a way 24. This slide 23 connects by a link 25 with one end of a bell crank lever 26, the other end of said lever being connected by a link 27 with a slide rod 28. The slide rod 28 is through an arm 29 connected w th the shaft 15, said shaft having two fixed collars 3O thereon between which the collar on the arm 29 lies about the shaft 15. It is apparent that the swinging of the lever 20 will effect the slid ing of the shaft 15 and thereby the movement of the head carried by such shaft. A pawl 31 on the lever 20 cooperates with a segmental rack 32 on one of the posts 3, this pawl being controlled by a lever mechanism 33 and serving to lock the shaft 15 in its adjusted position.

The turn ng of the barrel may be effected through a pulley 34 which has a key connection 35 with the shaft 14, said shaft having a longitudinally extending groove 36 in which the key may travel when the shaft is moved longitudinally. The pulley is supported between two of the uprights 3 and sleeves 37 lie between the pulley and the uprights to maintain the pulley in a central position, notwithstanding the longitudinal movementof the shaft 14. A housing 38 surrounds the pulley and is open at the topof the frame for the passage of the belt 39.

For centering the barrel with refernce to the turning heads, there is provided a centering means in the form of a support which positions the barrel so that its center is slightly below the center of rotation of the heads in order that, when the relative movement between the heads takes place, the chamfered chime engaging portions will cooperate with the chimes of the barrel, lift the latter off the centering means, and position such barrel properly in centered position on the heads free of the centering means, permitting the barrel to turn without interference with the centering means. This centering and supporting means, in this instance, comprises two bars 40 arranged substantially in parallel relation and formed with depressed portions 41 situated directly below the axis of turning of the turning heads. These supporting bars are preferably vertically adjustable and to this end may be secured together at opposite ends by cross bars 42, each cross bar having an adjusting means at opposite ends thereof.

This adjusting means, in this instance, em

bodies a vertically arranged screw, 43 mounted to turn'in an upright piece 44 and having the screw threaded portion thereof engaging nuts 45 formed in the ends of the cross pieces 42. At the upper end of each screw a handle 46 is provided which, when turned, will effect the elevation of that end 'of the cross piece 42 with which the screw engages. It is apparent that by this arrangement the bars 40 may be positioned at a height corresponding to the diameter of the barrel to be coated so that proper cooperation between the barrel and the turning heads may be established.

The coating of the barrel may be efi'ected in any suitable manner. In this instance, there is provided a plurality of brushes 47 secured in angular relation to arms 48 adjustably secured to a rock shaft 49. This arrangement permits the brushes to be arranged out of line with each other so as to cooperate with a barrel which tapers toward its end. The shaft 49 may be positioned in any one of the bearings 50 so as'to be brought difierent distances from the axis of rotation of the barrel in order to operate on barrels of different diameter. Movement of the shaft 49 may be efl'ected through a treadle 51 which has an arm 52 adjust ably connected to alink 53 which is in turn adjustably connected to an arm 54 on the shaft 49. The brushes 4'? operate in the coating receptacle and serve to apply or distribute the paint on the barrel. Also cooperating with the barrel are spreading brushes 55 which are carried by arms 56 adjustably connected to a rock shaft 57 so that the brushes may bepositioned on the shaft to correspond to the shape of thebarrel. The shaft 57 may be operated by hand by a pieces 42 at 61.

lever arm 58 to move into and out of engagement with the barrel, these brushes serving to spread the paint which is distributed on the barrel by the brushes 47.

After the barrel has been painted, the heads are separated and the barrel falls on the bars from which it is displaced by any suitable means onto a runway 59. To the end of facilitating the movement of the barrel from the rods to the runway 59 notwithstanding the adjustment of the bars 40 to correspond with barrels of different diameters, two runner bars 60 are provided which are pivotally connected to one of the cross These runner bars are in turn connected at their free ends by a cross bar 62 which projects at 63 beyond the runner bars 60 to rest upon the runner bars 59.

The operation of the invention will be understood from the foregoing description, but it may be summarized as follows:

The machine is first adjusted to correspond to the diameter of the barrel to be operated upon. A barrel is brought to the supporting bars 40 by hand or otherwise, so that it is centered in the depressions 4:1. The lever 20 is then shifted to cause the barrel to be engaged by both of the heads. This engagement lifts the barrel off of the bars 40 and causes it to become centered with reference to the heads. The brushes are then brought into contact with the barrel, first' the distributing brushes to apply a proper amount-of paint, and then the spreading brushes to spread the paint evenly over the barrel. After the barrel is properly painted,

the rotation thereof is discontinued and the lever 20 is operated to separate the heads. The barrel falls onto the bars 40 and is pushed off by hand or otherwise onto the runner bars from which'it travels to the runway 59 to any desired destination.
